Question

Please explain this, I have no idea how to do it!

t2 = 81
What does T stand for? Round to the nearest tenth if necessary.

Answer 1

t = 9

Explanation:

t² = 81

√t² = √81

t = 9

Answer 2

t=40.5

Explanation:

T likely stands for time. but I suspect you haven't given us the full question because the piece you gave us doesn't determine what T stands for. either way, t is your variable. could be substituted for x or any other variable.

t2=81

isolate t

/2

t= 81/2

t= 40.5
